How we worked it out

Selenium

  • Servings: 100 ÷ 1 per serving = 100
  • In the pack: 100 × 200 µg = 20 mg
  • £7.96 ÷ 20 mg × 100 µg = 3.98p per 100 µg selenium
  • A week 3.98p × 7 = 28p · a month × 30 = £1.19 · a year × 365 = £14.53
  • Amount per serving: stated on the label.

Vitamin E

  • Servings: 100 ÷ 1 per serving = 100
  • In the pack: 100 × 20.1 mg = 2.01 g
  • £7.96 ÷ 2.01 g × 268 mg = £1.06 per 268 mg
  • A week £1.06 × 7 = £7.43 · a month × 30 = £31.84 · a year × 365 = £387.39
  • Amount per serving: stated on the label.
